Figure below shows a sway frame with 14times14 inch columns

Question

Figure below shows a "sway" frame with 14×14 inch columns and 14×26 in beams. The moments computed for column AB are from the frame analysis and represent the moments about x-x axis of the column cross section.

Mxuns=650 in.kips, Mxus = 110 in-kips and Pu = 105 kips.

In the direction perpendicular to the plane, the framing is considered as "no-sway" and theoretically, there is no moment transferred to the column; thus use the minimum amount of moment based on emin (however, you will need to use magnification factor for this moment also).

Use βd = 0 for the "sway" frames and 0.4 for "no-sway" frames for all calculations. Use Cm=1 when computing the magnification factor for the moment with respect to y-y axis of the column.

fy = 60,000 and f'c = 4,000 psi.

1. Compute the design moment with respect to the x-x axis of the cross section.

2. Compute the design moment with respect to the y-y axis of the cross section.

3. Using the results from Parts 1 and 2, check if the column design is acceptable using Breseler's equations

Answer 1

In accordance to the illustrated figure, you have to provide solution by solving the numerical problem of civil engineering. Question: Figure illustrates ‘sway’ frame by means of 14x14 inch columns and 14x26 in beams. The moments calculated for column AB are from the frame analysis and symbolize the moments regarding x-x axis of the column cross section. In direction perpendicular to the plane, the framing is taken as ‘no-sway’ and theoretically, there is no moment transported to the column; therefore make use of the minimum amount of moment based on the emin. Consider all the information and data provided in the assignment and on that behalf respond to: 1) Calculate the design moment with respect to the x-x axis of cross section. 2) Calculate the design moment with respect to the y-y axis of cross section. 3) By using the results from Parts 1 and 2, prove if the column design is acceptable by using Breseler's equations.
